Potential evapotranspiration derived from HadUK-Grid 1km gridded climate observations 1969-2024 (Hydro-PE HadUK-Grid)
Gridded potential evapotranspiration calculated from HadUK-Grid gridded observed meteorological data at 1 km resolution over the United Kingdom for the years 1969-2024. This dataset contains two potential evapotranspiration variables: daily total potential evapotranspiration (PET; kg m-2 d-1) and daily total potential evapotranspiration with interception correction (PETI; kg m-2 d-1). The units kg m-2 d-1 are equivalent to mm d-1. The data are provided in gridded netCDF files. There is one file

Useful for
- Use cases llm-inferred
- PET inputs for FRA water balance and drought assessments on UK catchments · Evaporation-loss estimates for drainage and SuDS water balance modelling · Gridded PET forcing for catchment rainfall-runoff model calibration
- Audience llm-inferred
- hydrologists · flood consultants · water resources engineers · drainage engineers
Limitations
- Constraints llm-inferred
- PET is modelled (Penman-Monteith for well-watered grass), not observed evapotranspiration · Derived from HadUK-Grid station-based data; accuracy may be lower where station density is sparse · Netcdf only; no GeoTIFF or other formats listed · Versions differ by year (HadUK-Grid v1.0.3.0 to v1.3.1.ceda), so check version changes when combining periods · Scripted bulk download needs a personal access token
